DEVICE FOR HOLDING RIVETS.

SPECIFICATION forming part of Letters Patent No. 367,314, dated July 26, 1887.

Application filed December 6. 1886. Serial No. 220,781. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM OLDMAN, J r., a citizen of the United States, residing in Buffalo, in the county of Erie and State of'New York, have invented certain new and useful Improvements in Devices for Holding Rivets while Riveting, of which the following is. a specification.

The object of my invention is to provide the means for holding rivets While riveting asteanr boiler, or for other purposes, and will be fully and clearly hereinafter described and claimed, reference being had to the accompanying d rawings, in which- Figure l is a vertical central section through the outer casing of the device, showing a side elevation of the riveting-bar, the rubber or elastic disk, the reducing-bar and the handle orlever for operating it, also a section through a portion of a boiler. Fig. 2 is a plan or top view of the device. Fig. 3 is a detached side Fig. 4 is a bottom view of a removable rubber disk. Fig. 5 is a vertical central section through the same and the bolt by which it is secured in place; and Fig. 6 is a top view of the rubber disk or short cylindrical block.

In said drawings a portion, 1, of a steamboiler is shown, showing the device in place within a boiler and holding a rivet in position to be riveted.

2 is an outer cylindrical portion or casing. It is preferably made of wrought-iron tubing about two and one-halfinches inside diameter; but may be larger or smaller,if desired, and is slotted to receive the lever 12. I

The riveting-bar 3 is usually made of two or two and a quarter inch round iron, and is provided with a tapering or reduced portion, 4, at the top, of cast-steel,which is preferably hardened or tempered.

It is provided with a depression or recess, 5, on the top,(see Fig. 1,) enough being broken away to show this depression, which is made so as to conform to the shape of the head of the rivet a. 7

This rivetingbar is made easily removable. Below it is a rubber disk or short cylindrical block, 6, to act as a cushion. Below the rubber disk 6 is a reducing-block, 7, which rests on the end 15 of the lever 12. All these parts are made enough smaller than the casing 2 as to be easily removable.

8 and 9 represent two plates rigidly secured to the side of the casing and perforated with holes 10 and 11.

12 represents a lever having a handle, 13.

It is adapted to be readily secured in any of I the holes 10 or 11 by means of the bolt 14. The object of these holes 10 and ll is to provide the means for adjusting the lever 12 up or down to any point desired. The oiiice of the rubber block 6 is to relieve the reducingbar 7, the lever 12, and the hand while holding it from the concussion produced by the hammering of the rivet.

16 represents a small removable pin adapted I to fit into the rivet-holes 17 in the lower part of the boiler for keeping the lower end of the device in position when using it. This pin is easily removable by unscrewing it from the cap 18. When there are no holes in the bottom of the boiler,this pin may be removed and the rubber disk 19 put win its place by means of the bolt 20. (See Figs 4 and 5.) The depression 21 allows the head of the bolt to pass in, so as to be out of the way,-and it may be deep enough to allow the head of the bolt to pass in far enough to allow room for the disk i torest on the boiler while the head of the bolt dle 13 to force the riveting-bar 3 up firmly .agaiust it, in which position it is held securely,

as shown in Fig. 1, until riveted.

There may be several of the bars 3 and 7,0f different lengths, so that the device may be easily and readily adjusted and be used in large or small boilers of various sizes.

For very light riveting the reducing-bar or the cushion, or both, may sometimes be dis-- pensed with and the riveting-bar made long enough to adapt it to the use required; but for general purposes it is best to have both.

I claim-as my invention-+ 1. A device for holding rivets while riveting, consisting of an outer case or tube, a vertically-adj ustable lever and handle, a rivetingbar' having a depression to receive the head of the rivet, a rubber disk or cushion, and a re dueiug-bar, all being easily removable from 3. The combination of the case 2, the rivet the outer case and combined for joint operaiug-bar 3,haviuga depression, 5, and the vertion, substantially as and for the purposes det-ically-adjustable handle 12 13, all being easily scribed. removable from the case 2, as and for the pur- 5 2. In a device for holding rivets, the composes described.
